Headset Ear Cushions for Plantronics SupraPlus/Entera — replacement black Donut style (MPN 40709-01)

Replacement Donut-style ear cushions designed for Plantronics SupraPlus and Entera on-ear headsets. These black soft foam rings fit over the headset speakers to restore comfort, improve hygiene and extend the usable life of the headset. The cushions are shaped to sit around the ear speaker without altering headset fit or microphone position, providing a straightforward refresh when original pads are worn or damaged.

Advantages

Soft open-cell foam provides immediate cushioning while maintaining acoustic transparency for clear voice transmission. The donut shape ensures even pressure distribution across the ear contact area and allows ventilation to reduce heat buildup during extended wear. The simple slip-on design allows quick replacement without tools and helps maintain a clean surface that is easy to wipe down between shifts or users.

Suitable for

• Office headsets used for daily voice calls and videoconferencing
• Call centres and helpdesk environments with shared headsets
• Home offices where original ear pads are worn, torn, or missing
• Environments requiring improved hygiene and easy maintenance of headsets

How to use

Align the foam ring with the headset speaker housing and stretch the inner opening over the speaker until the cushion sits evenly around the rim.

Usage recommendations

Replace cushions when foam shows visible wear, tears, or compression that affects comfort or sound; check regularly in shared environments. Store spare cushions in a cool, dry place away from direct sunlight to prevent premature degradation.
